Description

Ion generating device and manufacturing method

Technical Field

The present invention relates to an ion generating apparatus and a method of manufacturing the ion generating apparatus.

Background

Conventionally, ion generators have been used to purify, sterilize, deodorize, and the like indoor air.

Generally, an ion generating device includes a discharge electrode that generates ions by discharge. In the ion generating device, for example, ions are generated by generating corona discharge between the leading end of a discharge electrode to which a high voltage is applied and an induction electrode.

As a discharge electrode for generating ions by applying a high voltage in this manner, a brush-shaped discharge electrode in which root portions of a plurality of fibrous conductors are bundled is known.

For example, patent document 1 discloses a dust collecting device including a discharge electrode formed by bundling thin wires in a brush shape, and a plurality of induction electrodes provided at intervals. Patent document 2 also discloses an ion generator including a discharge electrode and an inductive electrode similar to those of patent document 1.

In such a brush-shaped discharge electrode, when a high voltage is applied, the tip ends of the thin wires, that is, the thin wires on the side not bundled are electrically repelled and spread. Therefore, when such a brush-shaped discharge electrode is used, the amount of ion generation increases when the same voltage is applied, for example, as compared with when a needle-shaped discharge electrode is used. As a result, good ion release can be performed.

In order to prevent leakage between the discharge electrode and the circuit board of the ion generating device by preventing the circuit board from being exposed, the base of the discharge electrode is embedded in the resin so that only a part of the tip of the discharge electrode is exposed.

For example, patent document 3 discloses a dc static eliminator in which the inside of an insulating holder is filled with a resin, a substrate provided with discharge needles is embedded in the resin together with the base portions of the discharge needles, and only a part of the discharge needles is protruded from the surface of the resin.

Disclosure of Invention

Technical problem to be solved by the invention

However, in the devices of patent documents 1 and 2, if the tip of the bundle of thin wires is spread in the brush-shaped discharge electrode, the tip may contact the surface of the device. In this case, since a high voltage is applied to the thin wire, an abnormal discharge occurs from the thin wire to the surface of the device, and the amount of ions generated may decrease. Therefore, it is necessary to keep the thin wire from contacting the surface of the device. In particular, as shown in patent document 3, when the surface is the surface of the filled resin, the surface level of the resin varies depending on the filling amount of the resin. Therefore, when filling the resin, the surface level of the resin must be properly controlled so that the fine wire does not contact the surface of the resin.

The present invention has been made in view of the above problems, and an object thereof is to provide an ion generating device and the like capable of appropriately controlling the surface level of a resin filled therein.

Means for solving the problems

In order to solve the above problem, an ion generating apparatus according to an aspect of the present invention is an ion generating apparatus for generating ions from a discharge electrode by means of discharge, including: the discharge electrode has a tip end portion having a plurality of linear conductors and a base end portion having the plurality of conductors mounted thereon; the ion generating device comprises: a housing having a housing portion for housing a part of the proximal end portion; and resin filled in the accommodating part; the ion generating device further includes a marking member indicating an upper limit of a surface level of the resin.

In order to solve the above-described problem, a method of manufacturing an ion generating device that generates ions from a discharge electrode by electric discharge according to an aspect of the present invention is a method of manufacturing the ion generating device, including: a placement step of placing a part of the proximal end portion of the discharge electrode in a housing portion of the housing; and a filling step of filling resin into the accommodating portion; in the filling step, the resin is filled to less than an upper limit of the surface level indicated by the identification member.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail.

[ embodiment mode 1 ]

First, an embodiment of the present invention will be described with reference to fig. 1 to 5.

Fig. 1 is a perspective view showing a schematic configuration of an ion generating device according to the present embodiment. Fig. 2 is a front view showing a schematic configuration of the ion generating apparatus, fig. 3 is a plan view showing a schematic configuration of the ion generating apparatus, and fig. 4 is a side view showing a schematic configuration of the ion generating apparatus. In addition, fig. 1 to 4 show the state before filling with the resin. For convenience of explanation, fig. 1 shows a state in which a part of the cross beam 81 of the protective plate 62 provided in the ion generating device is missing.

As shown in fig. 1 to 4, an ion generating apparatus 1 of the present embodiment includes: a rectangular case 10, a transformer drive circuit substrate 12, a high-voltage transformer 13, a discharge electrode substrate 14, a cover 15, an inductive electrode substrate 20,

protective plates

61, 62, and a regulating member 100.

The case 10 is box-shaped with an opening on the top surface and is made of insulating resin. A recess 90 is provided in a side surface of the case 10. A plurality of connection terminals 91 for external connection are provided in the recess 90. In the case 10, a transformer drive circuit substrate 12, a high-voltage transformer 13, an inductive electrode substrate 20, and a discharge electrode substrate 14 are housed in this order from the front. The inductive electrode substrate 20 and the discharge electrode substrate 14 are provided at positions overlapping in the vertical direction, and the inductive electrode substrate 20 is provided above the discharge electrode substrate 14.

A lid 15 is provided on the upper surface of the case 10 so as to cover the transformer drive circuit board 12 and the high-voltage transformer 13. An opening 15a is formed in the lid 15 at a position corresponding to the inductive electrode substrate 20 and the discharge electrode substrate 14. Further, the case 10 and the lid 15 constitute a housing.

The plurality of connection terminals 91 are formed of a conductive film, and may be formed by, for example, printing, plating, sputtering, cvd (chemical Vapor deposition), or the like. The conductive film is made of, for example, copper (Cu), aluminum (Al), gold (Au), or an alloy thereof, and has a film thickness of several tens of μm (for example, 35 μm).

A high-voltage transformer drive circuit is disposed on the transformer drive circuit substrate 12. The high-voltage transformer driving circuit is used to drive the high-voltage transformer 13 with an input voltage from the outside.

The high voltage transformer 13 is driven by the high voltage transformer driving circuit to boost the input voltage. The ion generating element is disposed on the induction electrode substrate 20 and the discharge electrode substrate 14, which are substrates for the ion generating element. The ion generating element generates at least one of positive ions and negative ions by applying a voltage boosted by the high-voltage transformer 13.

The ion generating element includes

discharge electrodes

21 and 22 provided on a discharge electrode substrate 14, and ring-shaped

induction electrodes

23 and 24 provided on an induction electrode substrate 20.

The discharge electrode substrate 14 is rectangular, and the

discharge electrodes

21 and 22 are arranged along the longitudinal direction of the discharge electrode substrate 14. The discharge electrode substrate 14 is provided such that a long side 14a, which is a side parallel to the arrangement direction of the

discharge electrodes

21 and 22, is parallel to the side 10a at the rear of the case 10.

The

discharge electrodes

21, 22 are disposed perpendicularly to the surface of the discharge electrode substrate 14. The discharge electrode 21 is attached to one side of the discharge electrode substrate 14, and the discharge electrode 22 is attached to the other side of the inductive electrode substrate 20. The discharge electrode 21 includes a plurality of linear conductors 25, and is a brush-shaped discharge electrode including a tip portion 31 formed in a brush shape and a base portion 33 to which the plurality of conductors 25 are attached. The discharge electrode 22 includes a plurality of linear conductors 26, and is a brush-shaped discharge electrode including a tip portion 32 formed in a brush shape and a base portion 34 to which the plurality of conductors 26 are attached.

The

tip portions

31 and 32 are portions before the

base end portions

33 and 34, specifically, portions from the tips of the conductors 25 and 26 bundled in a brush shape to the connection ends (contact ends) of the conductors 25 and 26 with the

base end portions

33 and 34. The linear form includes a filament form, a fiber form, and a wire form.

The distal ends 31, 32 of the

discharge electrodes

21, 22 are formed of a conductive material such as metal, carbon fiber, conductive resin, or the like. The outer diameter of each of the plurality of conductors 25, 26 at the

distal end portions

31, 32 is 5 μm or more and 30 μm or less. By setting the outer diameters of the conductors 25, 26 to 5 μm or more, the mechanical strength of the conductors 25, 26 can be ensured, and the electrical wear of the conductors 25, 26 can be suppressed. Further, by setting the outer diameters of the conductors 25 and 26 to 30 μm or less, the conductors 25 and 26 can be formed to be bendable like hairs, and the conductors 25 and 26 are easily diffused and wobbled.

The conductors 25 and 26 may be carbon fibers having an outer diameter of 7 μm or may be conductive fibers made of SUS (stainless steel) having an outer diameter of 12 μm or 25 μm.

The base end 33 of the discharge electrode 21 includes: a metal plate-like mounting portion 33a for mounting the discharge electrode 21 to the discharge electrode substrate 14; and a binding portion 33b for binding the plurality of conductors 25 of the tip portion 31 to the connection end. Similarly, the base end portion 34 of the discharge electrode 22 includes: a metal plate-like mounting portion 34a for mounting the discharge electrode 22 to the discharge electrode substrate 14; and a binding portion 34b for binding the plurality of conductors 26 of the tip portion 32 to the connection end.

The inductive electrode substrate 20 is provided above the discharge electrode substrate 14, and has

holes

20a and 20b formed at positions corresponding to the

discharge electrodes

21 and 22 extending upward from the discharge electrode substrate 14. The

inductive electrodes

23 and 24 are provided on the inductive electrode substrate 20 so as to extend along the outer peripheries of the

holes

20a and 20 b. In the present embodiment, the

inductive electrodes

23 and 24 are provided as wiring patterns on the inductive electrode substrate 20, but the present invention is not limited to this, and an annular plate member (metal plate) made of a conductor may be provided on the inductive electrode substrate 20.

The inductive electrode 23 is an electrode for forming an electric field with the discharge electrode 21, and the inductive electrode 24 is an electrode for forming an electric field with the discharge electrode 22. The discharge electrode 21 is an electrode for generating negative ions between itself and the inductive electrode 23 by discharge, and the discharge electrode 22 is an electrode for generating positive ions between itself and the inductive electrode 24 by discharge. The

inductive electrodes

23 and 24 are grounded.

The inductive electrode substrate 20 has a square periphery of the

electrodes

23 and 24, and a bridge portion 20c formed to connect the square portions. The width of the bridge portion 20c in the front-rear direction is narrower than the other portions.

Next, the

protection plates

61 and 62 will be described with reference to fig. 1 to 4.

The ion generating apparatus 1 is not limited to one that is mounted on a mounting table (not shown) in the state shown in fig. 1 to 4 until the apparatus is mounted on various electric devices after manufacture. For example, the ion generating apparatus 1 may be placed on the placing table in a state reversed from the above state. As described above, when the ion generating apparatus 1 is tilted in a manufacturing process or the like, the

discharge electrodes

21 and 22 may contact a bed (bed) such as the mounting table, and the brush portion may be broken (deformed) such as crushed.

Therefore, in the present embodiment, the

protective plates

61 and 62 for protecting the

discharge electrodes

21 and 22 are arranged in parallel with each other in the direction perpendicular to the arrangement direction of the

discharge electrodes

21 and 22, that is, in the short side direction of the discharge electrode substrate 14 and the inductive electrode substrate 20 (that is, in the direction parallel to the short side 14b of the discharge electrode substrate 14) with the

discharge electrodes

21 and 22 interposed therebetween.

The maximum height of the

protective plates

61 and 62 is larger than the height of the

discharge electrodes

21 and 22, and the

protective plates

61 and 62 are provided so as to protrude vertically above the lid body 15 or so as to protrude vertically above the

distal end portions

31 and 32 of the

discharge electrodes

21 and 22, or so as to protrude vertically above the lid body 15 integrally with the lid body 15.

The

protective plates

61, 62 are formed in a spectacle shape, respectively. Specifically, the protective plate 61 includes: a beam portion 71 formed of a horizontal plate parallel to the surface of the discharge electrode substrate 14;

support portions

72, 73 which are support columns for supporting both ends of the beam portion 71; and a support portion 74 which is a pillar that supports the central portion of the beam portion 71.

Openings are formed between the

support portions

72, 74 and between the

support portions

74, 73 adjacent to each other. Therefore, the protective plate 61 is provided with two

openings

61a and 61 b.

Similarly, the protective plate 62 includes: a beam portion 81 formed of a horizontal plate parallel to the surface of the discharge electrode substrate 14;

support portions

82, 83 which are support columns that support both ends of the beam portion 81; and a support portion 84 that is a support that supports the central portion of the beam portion 81.

Openings are formed between the supporting

portions

82, 84 and between the supporting

portions

84, 83 adjacent to each other. Therefore, the protective plate 62 is provided with two

openings

62a and 62 b.

The

support portions

72 and 73 are provided to protrude from both ends of the discharge electrode substrate 14 in the longitudinal direction so as to face each other. The support portion 74 is provided to protrude from the center of the discharge electrode substrate 14 in the longitudinal direction so as to face the

support portions

72 and 73.

Similarly, the

support portions

82 and 83 are provided to protrude from both ends of the discharge electrode substrate 14 in the longitudinal direction so as to face each other. The support portion 84 is provided to protrude from the center of the discharge electrode substrate 14 in the longitudinal direction so as to face the

support portions

82 and 83.

Thus, the

beam portions

71 and 81 are parallel to the long side 14a of the discharge electrode substrate 14, and extend from one end portion and the other end portion in the longitudinal direction of the discharge electrode substrate 14.

As for the

discharge electrodes

21, 22, when viewed through the protective plates 61, 62 (that is, when the ion generating device 1 is viewed from a direction parallel to the side 10a of the case 10), the discharge electrode 21 is exposed from the

openings

62a, 61b, and the discharge electrode 22 is exposed from the

openings

62b, 61 a.

Next, the regulating member 100 will be described with reference to fig. 1 to 5.

The regulating member 100 is provided so as to extend between the support portion 74 of the protective plate 61 and the support portion 84 of the protective plate 62. The regulating member 100 may be formed separately from the

protective plates

61 and 62, or may be formed integrally therewith. That is, the cover 15, the

protective plates

61 and 62, and the regulating member 100 may be integrally molded.

Fig. 5 is an upward sectional view taken along line a-a in fig. 2. As shown in fig. 1 to 5, the regulating member 100 has a contact portion 105 whose central portion is formed in a concave shape, and the contact portion 105 is supported by two

support portions

101 and 102. Therefore, the upper surface 105b of the contact portion 105 is located below the

upper surfaces

101a and 102a of the support portions 101 and 102 (on the side of the inductive electrode substrate 20). In other words, the restricting member 100 is formed in a stepped shape in which the supporting

portions

101 and 102 are upper-step portions and the abutting portion 105 is a lower-step portion.

The regulating member 100 is provided such that the lower surface 105a of the contact portion 105 contacts the bridge portion 20c of the inductive electrode substrate 20. Therefore, the regulating member 100 regulates the upward movement of the inductive electrode substrate 20, that is, the movement in the protruding direction of the

discharge electrodes

21 and 22.

The upper surface 105b of the contact portion 105 and the

upper surfaces

101a and 102a of the

support portions

101 and 102 are standard marking members used when filling resin into the region (housing portion 70) surrounded by the case 10 and the cover 15. Specifically, the upper surface 105b of the abutting portion 105 represents a lower limit of the surface level of the resin, and the upper surface 101a of the supporting portion 101 represents an upper limit of the surface level of the resin.

Here, if a state is considered in which ions are generated from the

distal end portions

31 and 32 of the

discharge electrodes

21 and 22 by applying a voltage to the

discharge electrodes

21 and 22, the plurality of conductors 25 are homopolar and thus electrically repel each other, and are electrically attracted to the

induction electrodes

23 and 24 of opposite polarity. Therefore, the conductor 25 is bent, and as a result, the brush tip has an open shape. The

upper surfaces

101a and 102a of the supporting

portions

101 and 102 are provided closer to the discharge electrode substrate 14 than the positions of the

distal end portions

31 and 32 of the

discharge electrodes

21 and 22 when a voltage is applied to the

discharge electrodes

21 and 22.

Therefore, by filling the resin so that the surface level of the filled resin becomes a height at which the upper surface 105b of the contact portion 105 is shielded and the

upper surfaces

101a and 102a of the

support portions

101 and 102 are not shielded, the surfaces of the resin can be prevented from coming into contact with the

distal end portions

31 and 32 of the

discharge electrodes

21 and 22.

(method of manufacturing ion generating apparatus)

Next, a method for manufacturing the ion generating device 1 will be described. In the following, a case where the lid body 15, the

protection plates

61 and 62, and the regulating member 100 are integrally molded will be described.

First, a transformer drive circuit substrate 12, a high-voltage transformer 13, a discharge electrode substrate 14, and an inductive electrode substrate 20 are disposed inside the case 10. At this time, the inductive electrode substrate 20 is disposed above the discharge electrode substrate 14 (disposing step).

Next, the transformer drive circuit substrate 12 and the high-voltage transformer 13 are covered with the lid 15, the

protection plates

61 and 62, and the regulating member 100, and the lid 15, the

protection plates

61 and 62, and the regulating member 100 are assembled so that the upper surface of the bridge portion 20c of the inductive electrode substrate 20 abuts against the lower surface 105a of the abutting portion 105 of the regulating member 100. At this time, the

discharge electrodes

21 and 22 protrude from the opening 15a of the lid 15, and the inductive electrode substrate 20 is exposed from the opening 15a of the lid 15. That is, a part of the

proximal end portions

33 and 34 of the

discharge electrodes

21 and 22 is accommodated in the region surrounded by the case 10 and the cover 15 (the accommodating portion 70).

Next, the housing portion 70 is filled with an insulating resin from the opening 15a of the cover 15, and the resin is cured (filling step). As the resin to be filled, for example, an insulating material such as an epoxy resin or a urethane resin can be used. The resin is filled in such a way that the surface level of the resin is above the upper surface 105b of the abutment portion 105 of the regulating member 100 and below the

upper surfaces

101a, 102a of the supporting

portions

101, 102 of the regulating member 100. That is, the resin is filled until the resin covers the upper surface 105b of the abutting portion 105 of the regulating member 100 and the

upper surfaces

101a and 102a of the supporting

portions

101 and 102 of the regulating member 100 and is exposed. The resin may not necessarily be filled from the opening 15a, and an injection port (not shown) may be provided to fill the resin from the injection port.

At this time, since the inductive electrode substrate 20 is embedded in the resin, the inductive electrode substrate 20 is moved by buoyancy of the filled resin, and it may be difficult to fix the positional relationship between the

discharge electrodes

21 and 22 and the

inductive electrodes

23 and 24. However, in the present embodiment, the lower surface 105a of the abutting portion 105 of the regulating member 100 abuts on the upper surface of the inductive electrode substrate 20. Therefore, the restricting member 100 restricts the upward movement of the inductive electrode substrate 20, and the inductive electrode substrate 20 does not move due to the buoyancy of the resin. Therefore, the inductive electrode substrate 20 can be disposed at an appropriate position.

As described above, in the method of manufacturing the ion generating device 1 of the present embodiment, the filling amount of the resin can be visually understood to be an appropriate filling amount of the resin as the surface level (liquid level height) of the resin, and therefore, the filling amount of the resin can be easily controlled. Therefore, when ions are generated, the leading ends 31 of the

discharge electrodes

21 and 22 are brought into contact with the resin, and abnormal discharge is generated on the surface of the resin, thereby preventing the occurrence of a decrease in the amount of ions generated.

[ embodiment 2 ]

As described below, another embodiment of the present invention will be described with reference to fig. 6. For convenience of explanation, members having the same functions as those described in the above embodiment are given the same reference numerals, and explanations thereof are omitted. In this embodiment, a difference from embodiment 1 will be described.

Fig. 6 is a sectional view showing a schematic configuration of the ion generating device 2 according to the present embodiment.

The ion generating device 2 of the present embodiment includes a restriction member 110 having a shape different from that of the restriction member 100 included in the ion generating device 1 of embodiment 1. Specifically, the abutting portion 105 of the regulating member 100 is supported by the two supporting

portions

101 and 102, and is formed in a concave shape. In contrast, the restricting member 110 of the present embodiment does not include the support portion 101. That is, the regulating member 110 includes a supporting portion (upper stage portion) 112 and an abutting portion (lower stage portion) 115, and is formed in a stepped shape in which an upper surface 115b of the abutting portion 115 is located below an upper surface 115a of the supporting portion 112 (on the side of the inductive electrode substrate 20).

Similarly to the contact portion 105 of the regulating member 100, the lower surface 115a of the contact portion 115 contacts the inductive electrode substrate 20, and the upward movement of the inductive electrode substrate 20 is regulated. Like the support portion 102, one end of the support portion 112 is connected to the support portion 84 of the protection plate 61, and the other end is connected to the contact portion 115. As with the regulating member 100, the upper surface 115b of the abutting portion 115 and the upper surface 112a of the supporting portion 112 are standard marking members used when filling the housing portion 70 with resin. That is, when filling the resin into the region surrounded by the case 10 and the lid 15, the resin surface is horizontally positioned above the upper surface 115b of the contact portion 115 and below the upper surface 112a of the support portion 112.

According to the present embodiment, as in embodiment 1, control of the surface level of the filled resin and control of the positional relationship between the

inductive electrodes

23 and 24 and the

discharge electrodes

21 and 22 are facilitated.

[ embodiment 3 ]

As described below, another embodiment of the present invention will be described with reference to fig. 7. For convenience of explanation, members having the same functions as those described in the above embodiment are given the same reference numerals, and explanations thereof are omitted. In this embodiment, a difference from embodiment 1 will be described.

Fig. 7 is a sectional view showing a schematic configuration of the ion generating device 3 according to the present embodiment.

The ion generating device 3 of the present embodiment includes the restricting member 120 having a shape different from that of the restricting member 100 included in the ion generating device 1 of embodiment 1.

The restricting member of the present embodiment includes two contact portions, i.e., the 1 st contact portion 125 and the 2 nd contact portion 126, and the 1 st contact portion 125 and the 2 nd contact portion 126 are supported by the

support portions

121, 122, and 123.

One end of the support portion 121 is connected to the 2 nd abutting portion 126, and the other end is connected to the support portion 84 of the protection plate 62. Similarly, one end of the support portion 122 is connected to the 1 st abutting portion 125, and the other end is connected to the support portion 74 of the protection plate 61. One end of the support portion 123 is connected to the 1 st abutting portion 125, and the other end is connected to the 2 nd abutting portion 126. Also, 3 supporting

parts

121, 122, 123 are provided in such a manner that the heights of the

upper surfaces

121a, 122a, 123a are the same. The

upper surfaces

121a, 122a, 123a are mark members indicating an upper limit of the surface level of the resin filled when the housing section 70 is filled with the resin.

The 1 st contact portion 125 and the 2 nd contact portion 126 have a concave shape similarly to the contact portion 105 of the regulating member 100. Similarly to the contact portion 105 of the regulating member 100 of embodiment 1, the lower surface 125a of the 1 st contact portion 125 contacts the upper surface of the inductive electrode substrate 20, and regulates the upward movement of the inductive electrode substrate 20. The lower surface 126a of the 2 nd contact portion 126 contacts the upper surface of the discharge electrode substrate 14, and restricts upward movement of the discharge electrode substrate 14.

The thickness of the 1 st contact portion 125 in the vertical direction is different from that of the 2 nd contact portion 126, and the upper surface 125b of the 1 st contact portion 125 and the upper surface 126b of the 2 nd contact portion 126 are set to be the same height. The upper surface 125b of the 1 st abutting portion 125 and the upper surface 126b of the 2 nd abutting portion 126 are mark members indicating the lower limit of the surface level of the resin to be filled when the resin is filled into the housing portion 70.

Here, the following is considered: the height of the upper surface 125b of the 1 st abutting portion 125 is different from the height of the upper surface 126b of the 2 nd abutting portion 126, and the lower limit of the surface level of the resin to be filled is set to either the

upper surfaces

125b, 126 b. In this case, it is considered that, when filling the resin, the operator confuses the lower limit of the surface level of the resin as one of the upper surface 125b of the 1 st abutting part 125 and the upper surface 126b of the 2 nd abutting part 126, and thus the filling amount of the resin is varied. In contrast, in the ion generating device 3 of the present embodiment, since the height of the upper surface 125b of the 1 st contact portion 125 is set to be the same as the height of the upper surface 126b of the 2 nd contact portion 126, the lower limit of the surface level of the resin is not erroneously set when the resin is filled.

According to the present embodiment, the 1 st contact portion 125 restricts upward movement of the inductive electrode substrate 20, and the 2 nd contact portion 126 restricts upward movement of the discharge electrode substrate 14. Therefore, when the housing portion 70 is filled with the resin, the movement of the discharge electrode substrate 14 is restricted in addition to the movement of the inductive electrode substrate 20, and the positional relationship between the

discharge electrodes

21 and 22 and the

inductive electrodes

23 and 24 is more easily controlled.

(modification example)

In embodiment 1 described above, the regulating member 100 is provided so as to extend across the opening 15a in a direction perpendicular to the arrangement direction of the

discharge electrodes

21 and 22, that is, in a short-side direction of the discharge electrode substrate 14 (that is, in a direction parallel to the short side 14b of the discharge electrode substrate 14). The regulating member 100 may be provided at a position where the upward movement of the discharge electrode substrate 14 can be regulated, and may be provided, for example, in a direction parallel to the arrangement direction of the

discharge electrodes

21 and 22, that is, in the longitudinal direction of the discharge electrode substrate 14 (that is, in a direction parallel to the long side 14a of the discharge electrode substrate 14). In other words, the position of the regulating member is not particularly limited as long as the regulating member can regulate the movement of the inductive electrode substrate 20 and can be a standard for filling resin.

In the above-described embodiment, the example in which the ion generating apparatus includes 1 restricting member is shown, but the ion generating apparatus may include a plurality of restricting members. For example, the discharge electrode substrate 14 may be provided with a regulating member for regulating the movement of the inductive electrode substrate 20 and a regulating member for regulating the movement of the discharge electrode substrate. In addition to the regulating member for regulating the movement of the induction electrode substrate 20, a marker member indicating the upper limit and the lower limit of the liquid surface filled with the resin may be provided.

The shape of the contact portion of the regulating member is not limited to the shape of each of the above embodiments, and may be any shape as long as the upper surface and the lower surface contact the inductive electrode substrate 20. That is, the shape of the cross section of the regulating member in the direction parallel to the short side 14b of the discharge electrode substrate 14 may be, for example, a U-shape bent downward. The position of the abutting portion is not particularly limited as long as the movement of the inductive electrode substrate 20 can be restricted.

[ embodiment 4 ]

Another embodiment of the present invention will be described with reference to fig. 8. In the present embodiment, an electric apparatus including an ion generating device will be described.

Fig. 8 is a plan view showing an example of the internal configuration of the electric apparatus according to the present embodiment.

Hereinafter, the case of using the ion generating apparatus 1 as an ion generating apparatus will be described as an example, but the same applies to the case of using the ion generating apparatuses 2 and 3 as ion generating apparatuses.

As shown in fig. 8, an example is shown in which an ion generating device 1 is mounted on a part of a fan casing 201 forming a ventilation path 202 that is a passage for guiding ions generated by the ion generating device 1 to the outside in an electric apparatus 200.

Therefore, the air blowing path 202 is provided with the ion generating device 1 and an air blowing device 203 for blowing air for transporting ions generated by the ion generating device 1. The ion generating apparatus 1 is provided downstream of the air blowing device 203 in the air blowing direction.

The blower 203 may also be a sirocco fan, a cross-flow fan, or other fans.

The ion generating device 1 may be integrally assembled to the electrical apparatus 200, or may be detachably provided to the electrical apparatus 200. By providing ion generating device 1 detachably to electrical apparatus 200, ion generating device 1 can be replaced or cleaned, and maintenance of electrical apparatus 200 is facilitated.

The electric device 200 is not particularly limited, and may be, for example, an ion generator, an air conditioner, a dehumidifier, a humidifier, an air cleaner, a fan heater, or other devices. The electrical device 200 may be used for housing or for vehicle mounting. The electric device 200 can be preferably used, for example, for conditioning air in a room of a house, a room of a building, a ward of a hospital, a vehicle interior of an automobile, an interior of an airplane or a ship of a ship, etc.

(modification example)

In the present embodiment, a case where the electric device 200 includes the air blowing device 203 is described as an example, but the air blowing device 203 is not essential. For example, even in the case of thermal convection, the ions generated by the ion generator 1 can be discharged to the outside.

[ conclusion ]

An ion generating device (1, 2, 3) according to embodiment 1 of the present invention is an ion generating device that generates ions from discharge electrodes (21, 22) by electric discharge, and is characterized in that: the discharge electrode has tip parts (31, 32) having a plurality of linear conductors (25, 26), and base end parts (33, 34) having the plurality of conductors attached thereto, and the ion generating device includes: a housing (case 10, lid 15) having a housing section (70) for housing a part of the base end section; and resin filled in the accommodating part; the ion generating apparatus further includes a marker member (limiting members 100, 110, 120) indicating an upper limit of the surface level of the resin.

According to the above configuration, by providing the marking member indicating the upper limit of the surface level of the resin filled in the storage portion, the surface level of the filled resin can be appropriately controlled. As a result, it is possible to prevent a decrease in the amount of ions generated due to abnormal discharge, current leakage, and the like from the plurality of conductors to the surface of the device.

The ion generating apparatus according to aspect 2 of the present invention may be configured such that, in aspect 1, the ion generating apparatus further includes: an inductive electrode for generating ions between the inductive electrode and the discharge electrode, an inductive electrode substrate which is provided with the inductive electrode and is accommodated in the accommodating part, and a limiting component (100, 110, 120) for limiting the upward movement of the inductive electrode substrate.

According to the above configuration, when the resin is filled into the housing portion, the inductive electrode substrate can be restricted from being lifted by the buoyancy of the filled resin. Therefore, the positional relationship between the discharge electrode and the inductive electrode can be appropriately controlled.

In the ion generating device according to mode 3 of the present invention, in mode 2, the marker member may be formed in a segment shape having an upper segment (

support portions

101, 102, 112, 121, 122, 123) which represents an upper limit of a surface level of the resin, and a lower segment (abutting

portions

105, 115, 1 st abutting portion 125, 2 nd abutting portion 126) which is the regulating member.

According to the configuration, the regulating member is integrally formed with the identification member, whereby the installation space can be reduced as compared with a case where the regulating member and the identification member are separately formed.

According to the aspect 3, the ion generating device of aspect 4 of the present invention may be configured such that the lower step portion represents a lower limit of the surface level of the resin.

According to the above configuration, since the lower portion indicates the lower limit of the surface level of the resin, the surface level may be set between the upper limit and the lower limit when the resin is filled, and the operator can easily inject the resin. Therefore, the surface level of the resin can be more easily controlled.

Further, since the lower-stage portion also facilitates control of the lower limit level of the resin, it is possible to prevent leakage from occurring between the discharge electrode and each portion of the ion generating device (for example, the transformer drive circuit substrate (12), the high-voltage transformer (13), the discharge electrode substrate (14), and the induction electrode substrate (20)).

In addition, the electric device (200) provided with the ion generating device having the above-described configuration can exhibit the same effects as described above.

A method of manufacturing an ion generating device according to aspect 5 of the present invention is a method of manufacturing an ion generating device according to any one of aspects 1 to 4, including: a placement step of placing a part of the proximal end portion of the discharge electrode in a housing portion of the housing; and a filling step of filling resin into the accommodating portion; in the filling step, the resin is filled to less than an upper limit of the surface level indicated by the identification member.

According to the above configuration, as in the above embodiment 1, by providing the marking member indicating the upper limit of the surface level of the resin filled in the storage portion, it is possible to provide the method for manufacturing the ion generating device capable of appropriately controlling the surface level of the filled resin.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in the respective different embodiments also fall within the technical scope of the present invention. Further, by combining the technical means disclosed in the respective embodiments, new technical features can be formed.
